If you are talking about the tiny little silver wheel thing, it seems to spin fine. I doubt it is because of that. Because during the last part of the field strip (taking out the bolt carrier), you have to rack the handle all the way back, and even then I'm getting that stuck segment. I think it might have something to do with the the part where the nozzle of the bolt carrier goes into the barrel set (the gold part).
Also, my rear sight does not stand up straight when I flip it up. It's a little bit slanted. I can push it in a little bit more to straighten it up if I push my finger against it, but when I let go to it slants back again. Is that supposed to be adjustable?
Thanks.
